Answer:
verdical lines have an undefined slope so it might be 4
343 Due to the fact that it is all the same length it will just multiply to 343 7*7*7=<span>343</span>
Answer:
x=6
Step-by-step explanation:
Step 1: Divide both sides by 17.
17x17=10217
x=6
Answer:
x = -5
y = -5
Step-by-step explanation:
If you multiply the top equation by negative 2, you can add it to the bottom equation and cancel out the x:
-2(-x + 5y = -20) --> 2x - 10y = 40
Add this to the bottom equation top to bottom:
2x - 10y = 40
-2x + 4y = -10
You get:
-6y = 30
Then solve for y:
y = -5
Plug this back in for either equation and solve for x:
-x + 5(-5) = -20
-x -25 = -20
-x = 5
x = -5
Your answers are:
x = -5
y = -5
